AI Technical Summary

Benefits of technology

This technology helps prevent damage caused when installing nuts onto sprouts or other parts during assembly processes such as screw fastening. It also improves the quality of these connections due to its ability to stop water leakage while maintain strong connection even after being subjected to high levels of stress over an extended period of use. Additionally, this design allows for better shock absorption without losing effectiveness because it does away with metal-topping threads at the bottom ends of the nut holes.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the tightness between bolted connections made by traditional methods like welding or soldering for better durability when exposed outdoors over time due to factors such as vibrations caused during use.

Abstract

The invention discloses a hexagonal flange face extrusion sealing bolt. The hexagonal flange face extrusion sealing bolt comprises a bolt body, a hexagonal nut, a round rod, an external threaded rod, a hexagonal round pipe, a flange and a spring, wherein the bolt body is composed of the hexagonal nut, the round rod and the external threaded rod, the vertically-arranged round rod is arranged on the lower end face of the hexagonal nut, the vertically-arranged external threaded rod is arranged on the lower end face of the round rod, the hexagonal nut, the round rod and the external threaded rod are coaxial, the outer diameters of the hexagonal nut, the round rod and the external threaded rod are gradually reduced, the round rod is sleeved with the coaxial hexagonal round pipe, the spring is connected between the hexagonal round pipe and the hexagonal nut, the round rod is sleeved with the spring, the lower end face of the hexagonal round pipe is provided with the coaxial flange, and the inner diameters of the hexagonal round pipe and the flange are the same. According to the hexagonal flange face extrusion sealing bolt, the spring is arranged between the nut and the hexagonal round pipe, and after the bolt is installed, the spring can press the flange on the installation face, so that good sealing performance is achieved between the lower end face of the flange and the installation face.
